Hopefully we can stick to the topic of this thread, i.e. not discuss the merits of Matt Clifford, I'm not holding my breath ;-)

Thanks to the 2012 interview of the singer of the choir that accompanied them in London we found out that Matt Clifford was the "The musical director of the Rolling Stones" and he's apparently been a charge of rehearsing the local choirs for YCAGWYW but he's been very "stealthy" !

Still, at some point during the 2013 tour (or maybe as early as LA/1 since I can hear a French Horn there) Matt Clifford got credited (in the tour program?) as being on French Horn. Not sure if it means they added a French Horn then but I can hear one on O2/25th too so...was it Chuck playing it on a synthesizer before Matt Clifford got credited?

Anyway are there any pictures of Matt Clifford ?

EDIT - yes, at least one from the Toronto report, thanks erikjjf for pointing it out : [www.iorr.org]
